hp to linux...Redhat upgrade ?

I wanted to get some thought from the list with regards to our migration plan. We have an oracle database(10.2.0.3) running on HP paric 11.11 and we want to move to Linux 6.5 and oracle 11.2.0.4. We have moved couple of our system from HP 11.31(oracle 11g) to Linux 6.5(oracle 11g) using cross platform incremental transportable tablespace. My question is how does one goes about using the same process for 10g to 11g migration and also hp to linux. When i say Linux i am talking about RedHat.

We were thinking to do the following

• Install oracle version 10.2.0.3 on Linux(5.5), cant use 6.5 as oracle 10.2 is not supported with 6.5
• If we do above, then i can migrate to 10.2.0.3 followed by an upgrade to 11g
• But the step above poses another huddle, oracle 11g is not supported on Linux 5.5
• so would we upgrade the RHEL version to 6.5 --> but if we upgrade to 6.5 and oracle remains on 10g that is not supported

I know we can use Golden Gate for something like this but we are trying to find a cheap options and not have additional cost(Golden gate), also if we were to go down using Golden Gate i am guessing Golden Gate version 10 is probably not supported for HP 11.11(source server).

What has the community done for such a migration project?
